"Kingdom of the Planet of the Apes" will be set some time after the events of its predecessor. According to a casting report, several ape societies will have emerged from the oasis in the film, which will be released in 2024, while a small group of humans have slowly recovered from the ape flu. Caesar's legacy is said to be ambivalent: While some ape societies have never heard of the hero, others turn events in their favor and establish their own empires based on false facts.
Due to this fact, it can be assumed that some time will have passed between Part 3 and Part 4. One of the many ape leaders is said to be particularly ruthless, enslaving other apes for his own purposes in order to gain possession of human technology. The main protagonist, probably Cornelius, fights with all means for the freedom of all apes and against their enslavement. On his way there he meets a young human woman who accompanies him, but also pursues her own interests. It is not yet known whether she, like many of her kind, has been rendered mute by the flu.
